篇1:NSEFC2B Unit 20 全单元教案1(人教版高二英语下册教案教学设计)

Ⅰ.Brief Statements Based on the Unit

Archaeological discoveries play an important part in the study of the history and culture of a country and at the same time can help us solve many mysteries.This unit mainly talks about two important archaeological discoveries:the King of Stonehenge in England and the Jinsha Ruins and the Sanxingdui Ruins Site in Sichuan Province.The discovery of the King of Stonehenge makes archaeologists think people in the Bronze Age had trade and cultural links with other parts in Europe.While the unearthed Jinsha Ruins again proved that it is likely that roots of Chinese culture are in Sichuan.They all have a historical significance on the study of the history and culture of the two countries.Besides,we need to review the use of “it”,especially when it is used in the subject position to stand for an infinitive or a clause.

Ⅱ.Teaching Goals

1.Talk about archaeological discoveries.

2.Express curiosity.

3.Review the use of “It”.

4.Create a flow chart.

Ⅲ.Background Information

1. Underwater Archaeology

The year was 1960.The eight team members were divers and scientists.The ancient wreck(船的残骸)was buried in the sands below the warm coastal waters off Turkey.Underwater archaeology was about to be born.

Archaeology is the study of ancient life,or how people lived thousands of years ago.The work of the archaeologist is to find and recover objects made by these ancient people and figure out how the objects were used.

The archaeologists on the team that found the ancient wreck usually worked on dry land.They knew the scientific methods used in dry-land archaeology.By adapting,or changing,these methods,the archaeologists could use them under water.After diving into the sea,the group used underwater cameras to take pictures of the wreck and its treasures.Next,they drew maps on plastic tablets to show where each object was located.Then,they used a tool that gently sucked the sand away from the treasures.Large objects were placed in baskets,which were brought up to the surface.Very heavy objects were pulled up with the aid of a balloon.

The recovered objects were put in a museum in Turkey.Archaeologists then brought the photos,drawings,and maps to the United States for further research.After seven years of study,the scientists learned that the wreck was 3 200 years old.

2.Spanish scientists dig up a monster of a bone

Spanish researchers digging in a semi-desert part of eastern Spain have found a bone from an animal more than 30 metres in length and weighing 50 tons.The upper leg bone measures 1.85 metres and weighs 150 kilograms.This indicated that it came from the equivalent of a male elephant.

Scientists believe the bone came from a Sauropod,a lizard-like dinosaur that lived from 145 to 65 million years BC.

If these guesses are confirmed,it would be the largest dinosaur discovered in Europe.

It could possibly be as big as a champion heavy weight like Argentinausorus,found in South America,which from the evidence of a foot and three ribs,was probably longer than 35 metres.

The four-legged Sauropods,which had tiny brains,vast stomachs and long necks and tails,are believed to have been vegetarians,eating large trees the way people crunch celery sticks.

(Teacher shows some sentences on the screen.)

T:Do the sentences A and B in each pair have the same meaning?

Ss:Yes.Both of the two sentences in each pair have the same meaning.

T:Are there any differences?Who’d like to try the first pair?

S10:The subject of Sentence A is an infinitive phrase,while that of Sentence B is “It”.In Sentence B,“It” is used in the subject position to stand for the infinitive phrase.The reason why the sentence is written like that is that we want to keep the balance of the sentence.Am I right?

T:Yes.you’re right.Sentence B is more usual in everyday English.The second pair,Li Ping,try please.

S11:In Sentence A,the subject is a that-clause,while the subject of Sentence B is “It”,which is used in the subject position to stand for a clause.

T:Very good.The sentence structure “It is+adj.+an infinitive/a clause”is very useful in learning English.(Teacher writes the sentence structure on the blackboard.)Can you make a sentence with the sentence structure?

S12:Let me try.It is dangerous to go out alone at night.

T:Good.Wang Wei,make a sentence with the structure.

S13:It is natural that a child should love its mother.

(Teacher writes the two sentences the students made on the blackboard.)

T:You all did very well.Now,please look at the screen.

(Teacher shows the following on the screen.)

In this pair,Sentence A and Sentence B have the same meaning.Sentence A includes a very useful sentence structure.Do you know what it is?

Ss:Yes.It is:It be+p.p.+that-clause.

(Teacher writes it on the blackboard.)

T:Look at the blackboard,please.Here “It”is also used in the subject position to stand for a clause,but it is different from what we reviewed just now.Is that so?

Ss:Yes.

T:The sentence pattern “It be+p.p.+that-clause”can often be changed into the sentence structure “People+vt.+that-clause”.The past participles used like that in the sentence structure are: reported, believed, thought, proven, known, hoped, suggested, etc.

(Teacher writes them on the blackboard.)

T:Are you clear about that?

Ss:Yes.

T:OK.Let’s do Ex.2 at Page 78.First do them by yourself,then check your answers with your partner.After a while,I’ll ask some of you to read out your sentences.

T:Well,besides the use as a preparatory subject or object,we all know “it” can be used to give special emphasis to almost any part of a sentence except the verb.Can you tell me the emphatic structure?

Ss:Yes.It is “It be+the emphasized part+who/that…”.

(Teacher writes the structure on the blackboard.)

T:Quite right.Now let’s look at the screen and do another exercise.(Teacher shows the following on the screen.)

Correct mistakes if there are any.

1.It is he that I want to see.

2.It is I who is leaving for London next week.

3.It was on Tuesday when Mrs Smith came.

T:Who’d like to do the first one?Any volunteer?

S1:Let me try,“him” should be used instead of “he”,because the emphasized part is an object.

T:Quite right.The second one?

S2:“is” after “who” should be replaced by “am” to agree with “I” in person and number.

T:…

S3:“when” should be replaced by “that” to give special emphasis to the adverbial of time.

T:You are all right.You’ve mastered this sentence structure very well.Now I will show you some other sentences.(Teacher shows them on the screen.)

1.It is my turn.

2.Let’s call it a day.

3.If the teacher sees you doing that,you will catch it.

4.Go ahead,we’ll make it in the end.

5.-I will study hard in the future.

-That’s it.

6.Take it easy.

T:Now please look at the sentences on the screen.I’d like you to translate them into Chinese.Any volunteer?

S1:轮到我了。

S2:今天就到这里吧。

S3:如果老师看到你这么做,你就会挨批评。

S4:继续干吧,我们最终会成功的。

S5:-今后我会努力学习的。

-这就对了。

S6:别着急。

T:Very good.We can see in these sentences,“it” has no special meaning.Is that clear?

Ss:Yes.

T:Well,now let’s do more exercises to further master the use of “it”.
